RESUMEN

Objective:To investigate the related factors of restlessness during the anesthesia recovery period in children with patent ductus arteriosus after interventional surgery.Methods:The clinical data of 92 pediatric patients with patent ductus arteriosus who underwent cardiac catheterization at Children's Hospital, Zhejiang University School of Medicine from November 2019 to October 2020 were retrospectively analyzed. These patients were divided into two groups based on the occurrence of restlessness during the anesthesia recovery period: a control group ( n = 67, without restlessness) and an observation group ( n = 25, with restlessness). Clinical data from both groups were collected and compared. Univariate and multivariate analyses were conducted to identify independent risk factors for restlessness during the anesthesia recovery period among pediatric patients with patent ductus arteriosus after interventional surgery. Results:Univariate analysis revealed no statistically significant differences in gender, age, temperament type, surgical duration, resuscitation room stay time, as well as blood pressure, heart rate, and blood oxygen saturation during the anesthesia recovery period between the two groups (all P > 0.05). However, the use of dexmedetomidine during surgery, preoperative anxiety, postoperative pain, and the use of antagonists were identified as risk factors for postoperative restlessness among pediatric patients with patent ductus arteriosus after interventional surgery χ2 = 9.03, 4.95, 5.84, 11.49, all P < 0.05). Multivariate regression analysis results further revealed that preoperative anxiety, postoperative pain, and the use of antagonists were independent risk factors for postoperative restlessness ( OR = 2.870, 4.083, 6.975, P = 0.029, 0.004, 0.002, 95% CI = 1.114-7.389, 1.555-10.722, 2.052-23.711), while intraoperative use of dexmedetomidine served as a protective factor ( OR = 0.318, P = 0.021, 95% CI = 0.120-0.839, all P < 0.05). Conclusion:The intraoperative use of dexmedetomidine, preoperative anxiety, postoperative pain, and the use of antagonists are identified as independent risk factors for postoperative restlessness in pediatric patients with patent ductus arteriosus after interventional surgery. It is crucial for clinicians to be aware of these factors and take preventive measures during the anesthesia recovery period to minimize the potential for harm resulting from postoperative restlessness.

RESUMEN

OBJECTIVE@#To study the working experience of COVID-19 care nurses.@*METHODS@#Twenty two nurses taking care of COVID-19 patients were interviewed by means of descriptive phenomenology. All the data were transcribed and recorded, and then processed into WORD documents. The Colaizzi 7 footwork was used to classify, encode, establish nodes and extract themes based on Nvivo11.0 software.@*RESULTS@#Two main themes were extracted: one is the positive feelings of nurses, including the sense of professional mission and pride, the sense of achievement and happiness, the improvement of self-worth and ability, the powerful support system and the power of role models; the other is the negative experience of nurses, including the worry and anxiety at work, the lack of experience and trust, the difficulty of work, and the inconvenience of isolating life.@*CONCLUSIONS@#s While fully affirming the work value of nurses, it is necessary for the society, hospitals and patients to give extensive and continuous support, care and respect to nurses, so as to stimulate their working enthusiasm and sense of professional achievement. Hospital managers need to implement all kinds of security work, meet the safety needs of nurses, pay attention to the physical and mental health of nurses, strengthen the training of nursing talents for critical and severe diseases and infectious diseases, improve the allocation of human resources, and enhance the ability of material allocation and reserve for major health events, so as to make adequate preparations for coping with public health events in the future.

RESUMEN

Objective To discuss the characteristics of extended-spectrum beta-lactamases(ESBLs)-producing Shigella and the relation between them and drug-resistance plasmid. Methods The suspicious ESBLs-producing isolates were screened by K-B disc diffusion method, and the ESBLs-producing strains were confirmed by confirmatory test recommended by the National Committee for Clinical Laboratory Standards. Furthermore, the partial blageneof these isolates were detected by PCR using universal primers for TEM, SHV, CTX-M-1 group, CTX-M-2 group and CTX-M-9 group, respectively. The entire blaCTX-M-9 and blaTEM were amplified by PCR using the primers outside the open reading frame (ORF) of these β-1actamases and products were directly sequenced. The conjugation experiment was performed to determine whether the resistance was transferable. Minimal inhibitory concentration (MIC) was detected with double agar dilution method. Results Of the 275 isolates, 12 strains were identified as ESBLs producers. Among them, 8 strains were CTX-M-14 carriers and 4 strains were CTX-M-3 carriers. All ESBLs-producing isolates are positive for plasmid conjugative transfer test. The transconjugants are only resistance to betalactams. Conclusions High resistance to beta-laetams in Shigella is caused by production of ESBLs in the local area. The ESBLs-produeing isolates can transfer the drug resistance through lateral transfer of plasmid.
